If you are looking for an easy way to display your Raspberry Pi's metrics in real time look no further.
The installation couldn't be simpler. If you already have a webserver and PHP configured on your Raspberry Pi you simply have to put the files in a sub-directory of your website and it just works!
I have installed it on the 5 production nodes of Pi Lab. Check it out here: pilab.dev/Node-1
The project is available on GitHub and is definitely worth a look.
Update: I have updated the Node Name in the footer of Pi Lab to link to the Pi Dashboard that has been setup for each node.
